Surpised there weren't any posts, maybe the alarms deterred some thief and the owner didn't know it. I have the Scorpio i900 with the RFID, perimeter and ignition disable. I also installed a enhanced LoJack system since we have excellent coverage here in CA., I secure the bike with a RoadLok and disc lock if the bike is unattended and it sleeps in a well secured garage at night. You can never stop a determined thief but if you can make it too time consuming or difficult they might pick an easier target.
